“…The absorption band at 1465 cm -1 can be assigned to N-C-N stretching vibration [39]. No absorption band was observed in the region of 1645-1630 cm -1 confirming the absence of vinyl groups in these polymers [41]. Compared with the FT-IR spectra before and after adsorption of Cd (II) ion, there were distinct band shifts and a new band at 918 cm -1 was appeared.…”

“…2-Thiozylmethacrylamide monomer (TMA) was synthesized as described previously [38]. Briefly, ice cold solution of 0.01 mol of methacryloyl chloride in 10 mL dichloromethane was added dropwise under stirring to 30 mL ice cold (0–5 °C) solution of dichloromethane containing 0.01 mol of 2-aminothiazole and 0.03 mol of triethylamine.…”

“…Other factors, including the coordination geometry, the coordination number of the metal ion together with the charge and the size of the ion are also known to play important roles in selectivity of IIPs [27,28]. To date, different IIPs have been synthesized and applied for selective preconcentration of a number transition metal ions, including Cu(II) [29–38], Cd(II) [39,40], Ni(II) [41–43], Zn(II) [44], Pb(II) [45], Fe(III) [46], Cr(III) [47], and Hg(II) [48,49]. …”

This work reports the preparation of a novel Cu(II)-ion imprinted polymer using 2-thiozylmethacrylamide (TMA) for on-line preconcentration of Cu(II) prior to its determination by inductively coupled optical emission spectroscopy (ICP-OES). Cu(II)-TMA monomer (complex) was synthesized and copolymerized via bulk polymerization method in the presence of ethyleneglycoldimethacrylate cross-linker. The resulting polymer was washed with 5% (v/v) HNO3 to remove Cu(II) ions and then with water until a neutral pH. The ion imprinted polymer was characterized by FT-IR and scanning electron microscopy. The experimental conditions were optimized for on-line preconcentration of Cu(II) using a minicolumn of ion imprinted polymer (IIP). Quantitative retention was achieved between pH 5.0 and 6.0, whereas the recoveries for the non-imprinted polymer (NIP) were about 61%. The IIP showed about 30 times higher selectivity to Cu(II) in comparison to NIP. The IIP also exhibited excellent selectivity for Cu(II) against the competing transition and heavy metal ions, including Cd, Co, Cr, Fe, Mn, Ni, Pb and Zn. Computational calculations revealed that the selectivity of IIP was mediated by the stability of Cu(II)-TMA complex which was far more stable than those of Co(II), Ni(II) and Zn(II) that have similar charge and ionic radii to Cu(II). A volume of 10 mL sample solution was loaded onto the column at 4.0 mL min−1 by using a sequential injection system (FIALab 3200) followed by elution with 1.0 mL of 2% (v/v) HNO3. The relative standard deviation (RSD) and limit of detection (LOD, 3s) of the method were 3.2% and 0.4 μg L−1, respectively. The method was successfully applied to determination of Cu(II) in fish otoliths (CRM 22), bone ash (SRM 1400) and coastal seawater and estuarine water samples.

“…The relative standard deviation (RSD) was 1.7 % for 1.00 μg mL −1 copper level (n=8), indicating favorable precision of the proposed method. A comparison of the proposed method with other literature (Shamsipour et al 2013;Shamsipur et al 2010;Yılmaz et al 2013;Ebrahimzadeh et al 2013;Lopes Pinheiro et al 2012;Luo et al 2012) is given in Table 3. …”

Novel Cu(II) ion-imprinted polymers (Cu-IIP) nanoparticles were prepared by using Cu(II) ion-thiosemicarbazide complex as the template molecule and methacrylic acid, ethylene glycol dimethacrylate (EGDMA), and 2,2'azobisisobutyronitrile (AIBN) as the functional monomer, cross-linker, and the radical initiator, respectively. The synthesized polymer nanoparticles were characterized by using infrared spectroscopy (IR), thermo gravimetric analysis (TGA), X-ray diffraction (XRD), and scanning electron microscopic (SEM) techniques. Some parameters such as pH, weight of the polymer, adsorption time, elution time, eluent type, and eluent volume which affect the extraction efficiency of the polymer were studied. In the proposed method, the maximum sorbent capacity of the ion-imprinted polymer was calculated to be 38.8 mg g(-1). The preconcentration factor, relative standard deviation, and limit of detection of the method were found to be 80, 1.7%, and 0.003 μg mL(-1), respectively. The prepared ion-imprinted polymer nanoparticles have an increased selectivity toward Cu(II) ions over a range of competing metal ions with the same charge and similar ionic radius. The method was applied to the determination of ultra trace levels of Cu2+ in environmental water samples with satisfactory results.
